How to add a handwritten signature to a PDF

Use a signature you wrote on paper—not a script font or a rushed finger drawing—and place it cleanly on a PDF.

Quick answer

Write your signature with dark ink on white paper, scan it in PDF Sign & Scan, save the cleaned signature, then choose it from the signature library while editing your PDF.

Step by step

  1. 01

    Write naturally

    Use the pen and signature style you normally use. Dark black or blue ink on plain white paper gives the cleanup tool the clearest edge.

    Scan, then inspect

    In Signatures, add a new signature and use Scan. Compare Before and After, then adjust Paper Cleanup or Ink Strength if a stroke looks faint.

A cleaner capture

  • Avoid lined paper, heavy shadows, and a pen color close to the paper color.
  • Do not crop through the first or last stroke.
  • Resize down rather than stretching a low-resolution signature up.

Questions

Do I have to draw on the iPhone screen?

No. The Scan mode is designed to capture the signature you write on paper. Drawing on screen is an optional second method.

Can I save more than one signature?

Yes. The app supports multiple named signatures in its signature library.
